Hi there!
I want to make a for loop inside of an other for loop, the first one shall read every line from a string array (which is created from a xml file) and the other loop shall read every character from the lines. Does anyone know how it works? Biggest problem is the second loop, how to read every single element from a line and also make a check if the element is a number. I’ve tried a lot of different functions but nothing works, perhaps the picture below makes my problem more understandable.
To make things clearer, below is a picture of the file I wanna read data from. For instance I want to pick the value 81977 (and hundreds of other values) and print it on the screen.
